Proportional Directional Valve 4WRZE10E1-85-7X/6EG24K31/A1D3M - Bosch Rexroth R900775508

On the 4WRZE10E1-85-7X/6EG24K31/A1D3M pilot oil supply and return both run externally, while the spool of symbol E1 releases up to 85 l/min nominal flow. That separation keeps pilot pressure steady even when working pressure runs up to the 315 bar operating pressure.

Benefits

• 85 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
• External pilot supply through X and external draining through Y, independent of the main circuit.
• Spool symbol E1, 3 switching positions on 4 ports.
• Command value +/-10 V, on-board electronics with position feedback, 24 VDC.
• Subplate mounting to ISO 4401-05-05-0-05, weight 9.14 kg.
• Pressure reducing valve in the pilot stage, NBR seals, UKCA conformity.

Application

This variant belongs in plants where several valves are fed from a shared pilot pressure network, for instance in test fields and large forming presses. External draining keeps the pilot stage free of back pressure in the tank line. Mounting follows the size 10 pattern.
